Mission statement of the second round of Iranian Cubesat Competition: 

To provide IoT service, it is intended to design a satellite constellation, comprising 3 to 5 6-U cubesats at LEO along with data transmission terminals, and ground stations network including telemetry reception and telecommand stations. Each terminal should have the opportunity of sending its data (packet of 4 kB) to the constellation at least once in every 12-hour period. The space segment of the constellation should relay  received data to a ground station (located at the participant’s discretion) in less than 12 hours following reception from terminal. The service area for terminal coverage includes the territory of Iran with the maximum possible peripheral area.
 

 Competition criterion: 

Participants will carry out system design (conceptual design) of the space segment and ground segment of a satellite constellation to fulfill the objectives of the mission statement. 
The space segment system design will include determining the orbital parameters of the satellites as well as conceptual design of the satellites’ systems.
The ground segment system design shall include conceptual design of telemetry station, telecommand station(s) and user terminals. User terminals will be designed based on IoT standards.

 Observations: 

• Participating teams, at their discretion, will determine constellation pattern, orbital parameters, satellites specifications, communication frequencies among users, satellites and grounds stations, and whether or not to incorporate ISL into the system. The satellites’ altitude willl be bound to 500-700 Km.
• Satellites will be 6-U cubesats with the weight not exceeding 10 kg. Satellites need not to be identical.
• Incorporating other satellites or ground facilities to fulfill the mission is not allowed.
• Operational life span of the constellation will be three years.
• Cost of the constellation design, build up and maintenance will be determined for the course of three years.
• User terminals will be designed in accordance with IoT standards.

 Participant’s performance assessment: 

Performance of the participants will be assessed based on appropriateness of the design, and criteria such as minimum implementation cost, maximum coverage area and maximum number of covered users.
